The testing has 3 different cases: 1. local mode: ocfs2 better than gfs2 2. two files mutiple nodes 3. same file mutiple nodes, for 2 and 3 gfs2 better than ocfs2 generally Just provide a reference here. I tried to make it as simple as possible, leaving all formating and mount options as default, and with fixed-size file(2GB) and buffer(4kb). Did you or anyone ever test performance for ocfs2? maybe we can discuss further on this topic in future;-) Thanks, Eric > > Thanks, > Junxiao. > > _______________________________________________ > Ocfs2-devel mailing list > Ocfs2-devel@oss.oracle.com > https://oss.oracle.com/mailman/listinfo/ocfs2-devel > _______________________________________________ Ocfs2-devel mailing list Ocfs2-devel@oss.oracle.com https://oss.oracle.com/mailman/listinfo/ocfs2-devel
